Vibrations arise when energy is introduced into the ground impulsively or periodically. On construction sites, sources range from percussive and ramming methods to controlled hydraulic processes. The choice of method is crucial for the vibration balance.

• Percussive methods (e.g., heavy hydraulic breakers) generate high, short-wavelength impulses with a broad frequency spectrum.
• Blasting works release large amounts of energy in a very short time; propagation and attenuation depend strongly on geology and charge data.
• Hydraulic splitting methods such as concrete splitters and hydraulic wedge splitters transmit forces slowly and in a controlled manner; vibration in the subsoil is significantly lower by comparison.
• Cutting and pressing methods such as concrete pulverizers, hydraulic demolition shears, Multi Cutters, steel shear and tank cutters work largely without percussive impulses; their vibrations are mostly local in nature and well controllable.
• hydraulic power packs influence the dynamics indirectly: steady pressure build-up and clean control help avoid load peaks and structural excitation.
